U.S. crude slumps after Greek votes no to bailout

TOKYO (Reuters) - Oil prices slumped in early Asian trade on Monday after Greeks rejected conditions of a rescue package from creditors on Sunday, throwing the future of the country's euro zone membership into further doubt. U.S. crude went into freefall after the resounding vote, falling more than $2 to $54.81 at 0828 Tokyo time. Brent was down more than 1 percent at $59.60.
